CVE-2020-16123 (GCVE-0-2020-16123)
Vulnerability from cvelistv5
Published
2020-12-03 23:15
Modified
2024-09-16 19:20
CWE
  • CWE-362 - Race Condition (Concurrent Execution using Shared Resource with Improper Synchronization)
Summary
An Ubuntu-specific patch in PulseAudio created a race condition where the snap policy module would fail to identify a client connection from a snap as coming from a snap if SCM_CREDENTIALS were missing, allowing the snap to connect to PulseAudio without proper confinement. This could be exploited by an attacker to expose sensitive information. Fixed in 1:13.99.3-1ubuntu2, 1:13.99.2-1ubuntu2.1, 1:13.99.1-1ubuntu3.8, 1:11.1-1ubuntu7.11, and 1:8.0-0ubuntu3.15.
